It was named after Antoine de la Mothe Cadillac, who founded Detroit, Michigan. The Cadillac crest is based on his coat of arms. By the time General Motors purchased the company in 1909, Cadillac had already established itself as one of America's premier luxury car makers.

The complete interchangeability of its precision parts had allowed it to lay the foundation for the modern mass production of automobiles. It was at the forefront of technological advances, introducing full electrical systems, the clashless manual transmission and the steel roof. The brand developed three engines, with its V8 setting the standard for the American automotive industry. Cadillac had the first U.S. car to win the Royal Automobile Club of the United Kingdom's Dewar Trophy by successfully demonstrating the interchangeability of its component parts during a reliability test in 1908; this spawned the firm's slogan "Standard of the World". It won the trophy again in 1912 for incorporating electric starting and lighting in a production automobile.
